Historic sidewalk and parts of original tramway uncovered during archaeology work at site
TWO HARBORS, Minn. (June 25, 2025) – Archaeology work at Split Rock Lighthouse has led to a historic discovery.
As part of this summer’s Trails and Landscape rehabilitation, crews removing asphalt near Keeper’s House #1 uncovered a historic sidewalk that once connected the house to the original barn. Archaeologists determined that this sidewalk also outlined the location of one of Split Rock’s original tramways, which was used to bring building materials up the cliff from Lake Superior during construction of the lighthouse.
As excavations continued, more discoveries came to light. The archaeology team also uncovered original rail ties and several railroad spikes from the tramway.
These discoveries provide a deeper understanding of Split Rock Lighthouse’s early history, helping historians better understand how the site was constructed, and how it has evolved into its current state.
Restoration work at the lighthouse includes improvements to existing pathways and restoring historic circulation patterns within the historic core. After the project is completed, guests will have access to a new view of where the historic hoist and derrick system was located and learn how it brought materials up from the water in 1909 during construction of the site. This new extended platform will provide views of the lighthouse, coastline, and Lake Superior.
The Minnesota Historical Society Archaeology Team will continue their work onsite as construction progresses.
This project was made possible by the people of Minnesota through an appropriation made by the Minnesota State Legislature and approved by the Governor.
